South Delta Improvements Program, Sacramento-San Joaquin Bay Delta, California

摘要

The Bureau of Reclamation (Reclamation) and the California Department of Water Resources (DWR) have made available for public review and comment the Draft EIS/EIR for the South Delta Improvements Program (SDIP). The proposed SDIP would (1) construct and operate a fish control gate at the Head of Old River; (2) construct and operate up to 3 flow control gates (one each in Middle River, Grant Line Canal, and Old River, near the Tracy Pumping Plant) to maintain adequate water quality and water levels available for agricultural diversions in the south Delta, downstream of the Head of Old River; (3) dredge various channels within the south Delta to improve conveyance; (4) construct extensions of up to 24 shallow agricultural diversions; (5) increase water deliveries by increasing the maximum diversion through the existing intake gates at Clifton Court Forebay to 8,500 cubic feet per second; and (6) implement an interim operations regime between December 15 and March 15 until the permanent gates are fully operable.
